So i installed the update on debian 12 using apt update; apt upgrade. This system doesnt have any mail server because the provider doesnt allow them. the upgrade wanted to install exim and friends. The hestia upgrade script failed due to lack of privileges to /var/log exim4
I restarted hestia again via systemctl restart hestia and everything is working.
I tend to manually upgrade hestia because it seems like the upgrade starts the service even if it isnt running. In other words i do ‘systemctl stop hestia’ unlesss i need to administer the machine. the upgrade script starts hestia back up
my other machine upgraded fine. It has a mail server
